Gastric Bypass Surgery Support Group
Gastric bypass (GBP) is any of a group of similar operative procedures used to treat morbid obesity, a condition which arises from severe accumulation of excess weight in the form of fatty tissue, and the health problems ("co-morbidities") which result. If you are considering gastric bypass or have had it, join the community where we share our experiences and find support.
Not that I know what you've tried but I'm preop still and my nut told me not to over buy protein powders because my tastes may change, so I've only been buying from GNC because they will take everything back, even after you've tried it. My nut also told me only to use protein isolate because post op you may become lactose intolerant and this type of protein has lactose removed.
